What is the Double Cube & how do I use it?

The doubling cube is a die with the numbers 2, 4, 8, 16, 32, and 64 marked on its sides. It is a fundamental element of backgammon strategy and is used by players to increase the original bet amount during gameplay.

How it works:

Either player can offer a double on their turn once the game has begun. Once a player has offered a double, the opponent can:

accept and double the original bet amount;

decline and forfeit the game at the original bet amount;

or automatically redouble ( to 4 times the original bet.

Once a player has offered a double that has been accepted, he cannot offer another double until his opponent has offered a double. Doubling offers can reach a maximum of 64x the original bet.
